The Water Wall Panel is the evaporation heating surface composed of many parallel pipes laid on the inner wall of the boiler furnace. Its main function is to absorb the radiant heat from the high-temperature flame or flue gas in the furnace, generate steam or hot water in the tube, and reduce the temperature of the furnace wall and protect the furnace wall. The Water Wall Panel has a simple structure, can save steel during manufacturing, and has good thermal insulation and air tightness, so the water wall used in the boilers of large-scale coal-fired power stations are basically membrane walls.
According to the structural type, there are three main types: plain tube type, membrane type and squeaked tube type.
The plain tube water wall is composed of a whole row of seamless steel pipes, and their structure is the simplest; the membrane water wall weld many rolled water-cooled fin tubes together with spot welding, so that they become a sealed combined heating surface, which can not only improve the air tightness of the furnace, reduce air leakage, but also better protect the furnace wall, reduce the weight of the furnace wall, simplify the structure; the water wall of the spur tube is to weld many pins with a length of 20~25mm and a diameter of 6~12mm on the water-cooled wall tube, and then apply chrome ore refractory plastic in order to reduce the heat absorption of this part of the water wall and increase the temperature of the combustion zone, it is suitable for occasions where fuel ignition is particularly difficult or some liquid slag discharge furnaces.
According to the layout part, there are two kinds of attached wall type and partition wall type (i.e., double-sided heating) water cooling wall.
The former is mostly partially embedded in the inner wall of the furnace wall and absorbs heat on one side, while the latter is mostly installed in the middle of the furnace chamber of a large boiler, separating the whole furnace into two independent parts that are heated on both sides.
(1)Improve combustion efficiency
The high temperature gas produced by combustion in the boiler furnace will be cooled through the water wall, and the water wall pipe will make the combustion process more complete by absorbing the heat released by the high temperature gas, thus improving the combustion efficiency.
(2)Control emissions
The role of the water wall also includes controlling the emission of harmful substances such as nitrogen oxides and sulfides produced during the combustion process of the boiler, making the chemical composition of the flue gas more stable and reasonable.
(3)Protect the boiler wall
The water wall can effectively reduce the temperature of the inner wall of the boiler furnace, reduce the time and opportunity of direct contact between the boiler wall and high temperature gas, and thus greatly extend the service life of the boiler
